The correct choice is Simple routing policy. It creates a basic DNS record that directs requests to a single resource and it matches a single Amazon EC2 web server when you do not want to split traffic or perform health based failover.

The Simple routing policy returns the same record for each query unless you change the record. It does not require multiple endpoints weights or health checks. For a single public site hosted on one EC2 instance this ensures Route 53 always points clients to that one endpoint.

Weighted routing is incorrect because it distributes traffic across multiple records using weight values and it requires multiple targets to divide traffic so it is not suitable for a lone endpoint.

Failover routing is incorrect because it is designed for active passive setups that rely on health checks to switch to a secondary resource and it requires at least a primary and an alternate target.

Latency-based routing is incorrect because it chooses the resource that gives the lowest latency from the request location which requires multiple regional endpoints to compare response times and it is not intended for a single endpoint scenario.
